摘要:
The present disclosure relates to methods for making elastomeric laminates that may be used as components of absorbent articles. The elastomeric laminates may include a first substrate, a second substrate, and an elastic material located between the first and second substrates. During assembly of an elastomeric laminate, a beam is rotated to unwind the elastic strands from the beam, wherein the strands may include a spin finish. First bonds are applied to bond discrete lengths of the stretched elastic strands with and between the first substrate and the second substrate, wherein the discrete first bonds are arranged intermittently along the machine direction. In addition, second bonds are applied between consecutive first bonds to bond the first and second substrates directly to each other, wherein the second bonds extend in the machine direction and may be separated from each other in a cross direction by at least one elastic strand.
